How to Make Fluffernutter Rice Krispie Treats
Step 1: Prep Your Pan
Begin by lightly greasing a 9×13-inch pan, or line it with parchment paper for the easiest cleanup ever. This simple step makes removing and slicing your Fluffernutter Rice Krispie Treats a total breeze—no sticky corners or stubborn bits left behind!
Step 2: Melt the Butter and Marshmallows
Place your largest sturdy pot on the stovetop over low heat and add the butter. Let it melt gently; the slower pace prevents browning and ensures an even, silky texture. Once melted, toss in all the mini marshmallows and stir constantly until they’re velvety smooth with no lumps.
Step 3: Mix in Peanut Butter, Marshmallow Fluff, and Flavorings
Take your pot off the heat—this is crucial to avoid scorching—and quickly stir in the peanut butter, marshmallow fluff, vanilla extract, and a pinch of salt. This fragrant, melty mix will become the luscious glue that binds everything together. Stir until the entire mixture is creamy, light, and uniform.
Step 4: Fold in the Cereal
Gently fold in the Rice Krispies cereal. Use a large spatula and stir with care to coat every crisp grain without crushing it. Your mixture should look airy, glossy, and packed with little pockets of marshmallowy goodness.
Step 5: Press and Cool
Quickly transfer the mixture to your prepared pan. Use a greased spatula or a piece of waxed paper to press the mixture evenly and firmly into the pan (just don’t smash it down too tightly or you’ll lose that gorgeous soft chew). Let your bars cool completely at room temperature so they set up perfectly before slicing into delicious, shareable squares.
How to Serve Fluffernutter Rice Krispie Treats
Garnishes
For a finishing touch, try drizzling your bars with melted chocolate for extra decadence, or swirl in a little extra marshmallow fluff across the top just before pressing everything into the pan. A sprinkle of flaky sea salt or crushed peanuts can also give your Fluffernutter Rice Krispie Treats an irresistible, gourmet vibe—just right for who wants something a little more elevated!
Side Dishes
Pair these treats with a cold glass of milk, a mug of hot cocoa, or a scoop of creamy vanilla ice cream for dessert perfection. If you’re serving a snack tray, they fit beautifully alongside fresh fruit, salty pretzels, or a handful of roasted nuts for that crave-worthy salty-sweet balance.
Creative Ways to Present
Cut your Fluffernutter Rice Krispie Treats into fun shapes using cookie cutters for parties, or layer squares between parchment in cellophane bags for sweet, homemade gifts. Stack several small bars on a platter and anchor them with festive skewers for an easy grab-and-go treat at any gathering.
Make Ahead and Storage
Storing Leftovers
Once cooled and sliced, store your Fluffernutter Rice Krispie Treats in an airtight container at room temperature. They stay freshest within the first three days—after that, they may start to lose a little of their perfect texture, but they’re still absolutely snackable!
Freezing
Want to stash away treats for later? Wrap tightly in plastic wrap and pop the bars into a freezer-safe bag or container. They’ll keep their texture and taste for up to two months. Thaw at room temperature for about an hour before serving and you’re good to go.
Reheating
While these bars don’t need reheating in the traditional sense, if you enjoy your Fluffernutter Rice Krispie Treats extra gooey, a quick 5–10 second zap in the microwave will make them soft and marshmallowy all over again!
FAQs
Can I use chunky peanut butter instead of creamy?
Absolutely! Chunky peanut butter adds a little extra crunch and nutty texture, making your Fluffernutter Rice Krispie Treats even more interesting. If you love that extra bite, swap it in—just remember, it will change the mouthfeel ever so slightly.
How do I keep Rice Krispie treats from sticking to my hands or spatula?
A light coating of non-stick spray or a dab of butter on your hands and spatula works wonders. You can also use a piece of waxed paper or parchment to press the mixture into the pan without any sticking drama.
Can Fluffernutter Rice Krispie Treats be made gluten-free?
Yes! As long as you use certified gluten-free Rice Krispies cereal and double-check your marshmallows and vanilla extract, your treats are entirely gluten-free and safe for those with sensitivities.
What’s the best way to slice the treats cleanly?
For neat squares, use a sharp knife and wipe it clean with a damp cloth between cuts. If the bars seem especially sticky, a little non-stick spray on your knife makes slicing a total breeze.
How long do Fluffernutter Rice Krispie Treats stay fresh?
They’re at their best within 2–3 days of making but can last up to five days in an airtight container. If you’re prepping ahead, freezing is a great option for longer storage.
Final Thoughts
